So he sat for the space of half an hour. Then he rose quickly to his feet. He replaced the shoes on their shelf with care, and stepped out upon the landing.
Two bedroom doors faced him on the other side of the passage. He opened that which was immediately opposite, and entered a bedroom by no means austerely tidy. Some sticks and fishing-rods stood confusedly in one corner, a pile of books in another. The housemaid’s hand had failed to give a look of order to the jumble of heterogeneous objects left on the dressing-table and on the mantelshelf—pipes, penknives, pencils, keys, golf-balls, old letters, photographs, small boxes, tins, and bottles. Two fine etchings and some watercolour sketches hung on the walls; leaning against the end of the wardrobe, unhung, were a few framed engravings. A row of shoes and boots was ranged beneath the window. Trent crossed the room and studied them intently; then he measured some of them with his tape, whistling very softly. This done, he sat on the side of the bed, and his eyes roamed gloomily about the room.
The photographs on the mantelshelf attracted him presently. He rose and examined one representing Marlowe and Manderson on horseback. Two others were views of famous peaks in the Alps. There was a faded print of three youths—one of them unmistakably his acquaintance of the haggard blue eyes—clothed in tatterdemalion soldier’s gear of the sixteenth century. Another was a portrait of a majestic old lady, slightly resembling Marlowe. Trent, mechanically taking a cigarette from an open box on the mantelshelf, lit it and stared at the photographs. Next he turned his attention to a flat leathern case that lay by the cigarette-box.
It opened easily. A small and light revolver, of beautiful workmanship, was disclosed, with a score or so of loose cartridges. On the stock were engraved the initials “J. M.”
A step was heard on the stairs, and as Trent opened the breech and peered into the barrel of the weapon, Inspector Murch appeared at the open door of the room. “I was wondering—” he began; then stopped as he saw what the other was about. His intelligent eyes opened slightly. “Whose is the revolver, Mr. Trent?” he asked in a conversational tone.
“Evidently it belongs to the occupant of the room, Mr. Marlowe,” replied Trent with similar lightness, pointing to the initials. “I found this lying about on the mantelpiece. It seems a handy little pistol to me, and it has been very carefully cleaned, I should say, since the last time it was used. But I know little about firearms.”
“Well, I know a good deal,” rejoined the inspector quietly, taking the revolver from Trent’s outstretched hand. “It’s a bit of a speciality with me, is firearms, as I think you know, Mr. Trent. But it don’t require an expert to tell one thing.” He replaced the revolver in its case on the mantelshelf, took out one of the cartridges, and laid it on the spacious palm of one hand; then, taking a small object from his waistcoat pocket, he laid it beside the cartridge. It was a little leaden bullet, slightly battered about the nose, and having upon it some bright new scratches.
“Is that the one?” Trent murmured as he bent over the inspector’s hand.
“That’s him,” replied Mr. Murch. “Lodged in the bone at the back of the skull. Dr. Stock got it out within the last hour, and handed it to the local officer, who has just sent it on to me. These bright scratches you see were made by the doctor’s instruments. These other marks were made by the rifling of the barrel—a barrel like this one.” He tapped the revolver. “Same make, same calibre. There is no other that marks the bullet just like this.”
With the pistol in its case between them, Trent and the inspector looked into each other’s eyes for some moments. Trent was the first to speak. “This mystery is all wrong,” he observed. “It is insanity. The symptoms of mania are very marked. Let us see how we stand. We were not in any doubt, I believe, about Manderson having dispatched Marlowe in the car to Southampton, or about Marlowe having gone, returning late last night, many hours after the murder was committed.”
“There is no doubt whatever about all that,” said Mr. Murch, with a slight emphasis on the verb.
“And now,” pursued Trent, “we are invited by this polished and insinuating firearm to believe the following line of propositions: that Marlowe never went to Southampton; that he returned to the house in the night; that he somehow, without waking Mrs. Manderson or anybody else, got Manderson to get up, dress himself, and go out into the grounds; that he then and there shot the said Manderson with his incriminating pistol; that he carefully cleaned the said pistol, returned to the house and, again without disturbing anyone, replaced it in its case in a favourable position to be found by the officers of the law; that he then withdrew and spent the rest of the day in hiding—with a large motor car; and that he turned up, feigning ignorance of the whole affair, at—what time was it?”
“A little after 9 p.m.” The inspector still stared moodily at Trent. “As you say, Mr. Trent, that is the first theory suggested by this find, and it seems wild enough—at least it would do if it didn’t fall to pieces at the very start. When the murder was done Marlowe must have been fifty to a hundred miles away. He did go to Southampton.”
“How do you know?”
“I questioned him last night, and took down his story. He arrived in Southampton about 6:30 on the Monday morning.”
“Come off” exclaimed
